The night before, combine all ingredients together. First mix the dry ingredients together and then add water. Mix the ingredients until the dough comes together. Cover it with a plastic wrap and let it sit for 12-20 hours on the countertop.
The following day, the dough should be wet, sticky and bubbly. Generously flour your hands and the baking sheet.
Take the dough (if it sticks, apply more flour to your hands) and form a baguette shape. Place it on a baking sheet and sprinkle a generous amount of flour on it. Score the top with a sharp knife and cover it with a towel. Let the dough rise in a warm place for 1-2 hours.
Preheat the oven to 450 °F. You will need to have 2 shelves in an oven. Fill a deep cooking sheet with 2 cups of hot boiled water, and place it on a lower level, inside your oven. This will make the bread crispy on the outside. Place the bread on the top rack. Remove water from the oven after 10 minutes. Keep on baking the bread for another 30 minutes or until golden crispy brown.
